CLOSER FOR GOLLAPSIBLE TUBES Filed Feb. 28, 1931 F. SZn/rz im@ Patentedy Dec. l, 1931 FREDERICK STANTON, F GRAND MERE, QUEBEC, CANADA CLOSERFOB COLLAIPSIBLE TUBES Application led February 28, 1331. 'Serial No.519,125.

This invention relates to collapsible tubes for tooth paste, shavingcream and the like, and has for one of its objects to provide a novelclosure for a tube of this character which shall embody a cap whichcannot be removed from the tube and cannot therefore become lost, andwhich will prevent waste of the contents of the tube and keep thecontents clean and prevent the access of air thereto.

The invention has for a further object to provide a closure of thecharacter stated which shall be simple and capable of being applied to atube without requiring any expensive changes in the method omanufacturing the tube, and which may be made of metal or any othersuitable material.

`lWith the foregoing and other objects in view, the nature of which willappear as the description proceeds, the inve-ntion consists in theconstruction, combination and arrangement of parts hereinafter fullydescribed and claimed, and illustrated in the accompanying drawings,wherein Figure 1 is a viewin side elevation of the upper portion of acollapsible tube equipped with a closure constructed in accordance withmy invention, the closure being shown inl opened position.

Figure 2 is a sectional view taken on the plane indicated by the line 22 of Figure 1.

Figure 3 is a sectional View taken on the plane indicated by the line 33 of Figure 1, and

Figure 4 is a view similar to Figure 3 with the closure in tube sealingposition.

Referring in detail to the drawings, 1 designates the bod 2 the breastand 3- the neck of a collapsi le tube for tooth paste, shaving cream andthe-like. In accordance yond the wall 'of the neck. A sleeve 7isrotatably mounted upon the neck 3 between the u per end of the breast2 of the tube and the ange 6 of the plug 5, the breast and with myinvention, the neck 3 is closed at flange serving to hold the sleeveagainst any axial movement on the neck. The sleeve 7 is provided with anopening 8, and it is adapt ed to be turned on the neck 3 to move itsopening into and out of re istration with the opening 4 ofthe neck; hesleeve opening 8 is larger than the neck opening et in order to permitthe free passage of the contents of the tube through these openings ywhen they are in registration. The sleeve 1s ce provided at its upperend with an annular flange 9 which extends radially beyond the flange 6of the plug 5, and which rovides means throughthe medium of w ich thesleeve may be turned to move its o ening 8 c5 into and out ofregistration with ing 4 of the neck 3.

To' adapt a collapsible tube for the application thereto of my improvedclosure, it is only necessary to rovide the neck 3 of the im tube withthe radia discharge o ening 4, and screw thread the inner wall of tlrieup r portion of the neck. After the sleeve 7 as been applied to the neck3, the .plug 5 is applied to the neck in order to secure the sleeve "15against removal from the neck and thus pre vent the loss of the same.The sleeve 7 has a snug fit on the neck 3, and in view thereof the'contents of the tube will be protected from the air and will be kept ina clean state. to When it is desired to withdraw some of the tooth aste,shaving cream or the like from the tube, the sleeve 7 is turned throughthe medium of the flange- 9 in order to register its opening 8 with theneck opening 4, and 85 after the desired quantity has been withdrawnfrom the tube the sleeve is turned to move its opening out ofregistration with the neck opening. As the closure consists merely ofthe plug 5 and sleeve 7, it is of very 90 simple construction, may bemanufactured at a comparatively low cost, and may be readily applied tothe neck 3 of thetube. As the sleeve 7 has a snug tit on the necki3, itwill be llleld against accidental turning on the nec While I havedescribed the principle of the invention, together with the structurewhich I now consider the referred embodiment u thereof, it is to be unerstood that the Struct e openture shown is merely illustrative and thatsuch changes may be made, when deeisfed7 es fall Within the scopo of thenvenien es claimed.

What is claimed is A collapsible tube having e neck @weide .1 with aradial discharge epenn e, e sleeve mounted on the neck and roved with a,radial opening and provide( al; is upper end Wih an outwardly dienedannuler enge, the sleeve being adaped'to be turned through the medium ofits flange to move its opening into and ou of regisis'ltion with sheneck opening, and a plug screw-threadedly engaged in the upper end ofthe neck and provided with an annule;` lie-Liege extendin radiallybeyond the neck and eontecting Wit the upper end o the sleeve tomaintenu the sleeve on the neck, the Bange of the sleeve projectingradially beyond the ange of the plug to permit it to be ifeadilygl'asped.

ln testimony whereof l hereunto affix my signature.
